The \u003cstrong\u003eCeiling Cassette CONFORTO MHCAS | 18,000 BTU - R410A\u003c\/strong\u003e is installed in the ceiling, toward the middle of the space, and distributes the air on four sides rather than from a single wall. The \u003cstrong\u003eMHCAS18DACFC\u003c\/strong\u003e cassette is paired with the \u003cstrong\u003eMHSZ118DACFC\u003c\/strong\u003e outdoor unit, whose \u003cstrong\u003evariable-speed compressor\u003c\/strong\u003e adjusts its speed to the room's demand.\u003c\/p\u003e\u003cp\u003eIts certified ratings are \u003cstrong\u003e20.0 SEER2\u003c\/strong\u003e, \u003cstrong\u003e12.5 EER2\u003c\/strong\u003e and \u003cstrong\u003e9.5 HSPF2\u003c\/strong\u003e. The system is \u003cstrong\u003eENERGY STAR\u003c\/strong\u003e certified with the \u003cstrong\u003ecold-climate designation\u003c\/strong\u003e under \u003cstrong\u003eENERGY STAR ID 2495140\u003c\/strong\u003e, the NEEP list still gives a heating capacity at \u003cstrong\u003e-30 °C\u003c\/strong\u003e, and its indicative LogisVert amount is $1,872 (only Hydro-Québec confirms the amount granted).\u003c\/p\u003e\u003ch3\u003eThe challenge of large rooms\u003c\/h3\u003e\u003cp\u003eIn an open area, a wall-mounted heat pump installed at one end heats and cools the zone in front of it well, and the far end much less. You end up raising the set point to reach the farthest corner, and the zone near the unit becomes too warm in winter or too cold in summer.\u003c\/p\u003e\u003cp\u003eThe cassette changes the geometry of the airflow: placed in the centre, it blows toward all four walls at once, through the louvres around its grille. The distances are shorter, the air mixes better and the temperature is more even from one end to the other. That is the main reason to choose a cassette in a large space.\u003c\/p\u003e\u003ch3\u003eThe spaces this size is meant for\u003c\/h3\u003e\u003cp\u003eThe 18,000 BTU size targets large rooms and open areas: a main floor where the living room, dining room and kitchen form a single space, a large finished basement, an open-plan office, a waiting room, a showroom. In a recent, well-insulated house, it can carry most of an open floor; in an older house with large original windows, it covers a smaller area.\u003c\/p\u003e\u003cp\u003eThe assessment done during the visit remains the only honest way to choose. We note the glass area and its orientation, the insulation, the ceiling height and how the space is used, then confirm whether this size fits or another one is more accurate.\u003c\/p\u003e\u003ch3\u003eWhere to place the cassette in an open area\u003c\/h3\u003e\u003cp\u003eThe geometric centre of the room is not always the right spot. We place the cassette between the living zones, away from the range and the hood, and never directly above a workstation, a table or a sofa. We take into account the light fixtures, the joists and the obstacles hidden in the ceiling.\u003c\/p\u003e\u003cp\u003eThe shape of the room also matters. In an L-shaped space, a single cassette does not always reach the end of the wing, and we say so during the visit rather than promise what the unit cannot do. In heating, warm air tends to stay high: the cassette's position and the louvre setting serve to bring it back toward the floor.\u003c\/p\u003e\u003ch3\u003eElectrical capacity, checked before the quote\u003c\/h3\u003e\u003cp\u003eA unit of this size needs a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e. In a house whose panel is already heavily loaded by the range, the dryer, the water heater and the baseboards, you have to make sure there is room left. We check the panel capacity during the visit. If an adjustment is needed, it appears in the written quote, not as a surprise on installation day.\u003c\/p\u003e\u003ch3\u003eLarge windows and summer\u003c\/h3\u003e\u003cp\u003eOpen areas often have large glass surfaces, and they are what drives the temperature up in the afternoon. In cooling, the cassette removes that heat and the moisture in the air, which condenses on the coil and flows out through the drain. The \u003cstrong\u003eEER2 of 12.5\u003c\/strong\u003e measures full-load efficiency during those hot hours. The \u003cstrong\u003evariable-speed compressor\u003c\/strong\u003e slows down as soon as the space is comfortable, giving long, steady cycles that dry the air better than repeated starts.\u003c\/p\u003e\u003cp\u003eBlinds lowered on the sunny side in the afternoon lighten the unit's work. This simple habit counts for more in a large glazed room than in a small bedroom.\u003c\/p\u003e\u003ch3\u003eWinter, according to the NEEP list\u003c\/h3\u003e\u003cp\u003eThe NEEP list's heating points are measured separately; we report each one as published.\u003c\/p\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003e15,600 BTU\/h at -8 °C\u003c\/strong\u003e (17 °F), with a \u003cstrong\u003eCOP of 2.24\u003c\/strong\u003e.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003e16,000 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F), with a \u003cstrong\u003eCOP of 1.75\u003c\/strong\u003e.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003e8,800 BTU\/h at -30 °C\u003c\/strong\u003e, with a \u003cstrong\u003eCOP of 1.27\u003c\/strong\u003e.\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eAt -30 °C, the COP of 1.27 remains above that of an electric baseboard, which is 1: even in extreme cold, the cassette produces more heat than it uses in electricity. Its capacity, however, drops by about half. For a large room, we therefore recommend keeping backup heating, the existing baseboards or another system, for those few nights of the year.\u003c\/p\u003e\u003ch3\u003eHow to read an HSPF2 of 9.5\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eHSPF2\u003c\/strong\u003e measures seasonal heating efficiency. It is calculated for a reference climate much milder than Quebec's, with few hours below freezing. It is useful for comparing models with each other, but it does not describe well what happens at -15 °C.\u003c\/p\u003e\u003cp\u003eFor a Quebec winter, the certified values at the cold points are more telling: a capacity of 89 % at -15 °C and a COP that stays above 1 at -30 °C. The \u003cstrong\u003eSEER2 of 20.0\u003c\/strong\u003e, for its part, indicates seasonal cooling efficiency: the higher it is, the less the unit uses for the same cooling over the summer. None of these ratings predicts a bill; insulation, settings and the winter itself make the difference.\u003c\/p\u003e\u003ch3\u003eVariable speed and R-410A\u003c\/h3\u003e\u003cp\u003eA \u003cstrong\u003eheat pump\u003c\/strong\u003e moves heat instead of producing it with a resistance element. In winter, the \u003cstrong\u003erefrigerant\u003c\/strong\u003e captures heat from the outdoor air and the cassette releases it into the room; in summer, the cycle reverses. The variable-speed compressor modulates its speed continuously, without running all-or-nothing, which stabilizes the temperature of a large room.\u003c\/p\u003e\u003cp\u003eThe system uses \u003cstrong\u003eR-410A\u003c\/strong\u003e, a refrigerant well known to technicians and found in a large share of the heat pumps installed in recent years. A tight installation, careful evacuation and annual maintenance ensure its reliability.\u003c\/p\u003e\u003ch3\u003eThe indicative LogisVert amount: $1,872\u003c\/h3\u003e\u003cp\u003eThe system is listed in Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e program, with an indicative amount of \u003cstrong\u003e$1,872\u003c\/strong\u003e for the owner of an existing home, according to the list in effect on the installation date.
